Yarrow Fewless joined CPP in 2005. As a project manager and engineer, he has been involved in all stages of the testing and analysis process. Yarrow has conducted wind tunnel studies for roof-mounted and ground-mounted solar structures, structural dynamics, cladding pressures, door operability, and pedestrian comfort. Yarrow holds a BS in mechanical engineering.
In addition to his project work, Yarrow has made important contributions to CPP’s tools and methods, including to the design and installation of CPP’s newest boundary-layer wind tunnel. Yarrow also played a key role in developing the CPP probe, a directional pressure-based sensor for measuring pedestrian-level wind speeds around buildings. This probe performs better in complex flow environments than other similar probes used in the industry. He also developed software to analyze pedestrian wind data, produce result figures and tables, and analyze wind climate data for pedestrian wind studies.
Yarrow is a member of the American Society of Civil Engineers Technical Council on Wind Engineering’s Structural Wind Engineering Committee and the Environmental Wind Engineering Committee, as well as the SEAOC Wind Design of PV Task Group. Yarrow also co-authored the 2014 ASCE publication, Engineering Investigations of Hurricane Damage.
